Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received part matches the HMC389LP4ETR designation and packaging specifications. Check for any end-of-life notices or production change notifications relevant to this specific batch. Ensure storage conditions comply with moisture sensitivity level requirements prior to soldering. Validate datasheet parameters against current official documentation before integration into final designs.

Selection Notes

Select this component when a fixed-frequency VCO solution is required in the 3.35-3.55 GHz range with integrated buffering. Consider the 46 mA supply current and 0-10 V tuning voltage constraints during power budget planning. Evaluate the -115 dBc/Hz phase noise performance against system jitter requirements. Compare the QFN package dimensions against available PCB real estate. Assess thermal dissipation capabilities based on the specified power consumption levels.
